[0002] The wine valve and bag-in-box (inner bag + outer bag) are integrated through thermoplastic sealing technology. The valve serves as the filling and taking interface, and is combined with the inert gas filling process to extend the shelf life.
[0003] An existing red wine valve includes a valve seat, a side wall of the valve seat is provided with a liquid inlet pipe, the liquid inlet pipe is connected to the valve seat, the bottom end of the valve seat is provided with a liquid outlet, a sealing plug for blocking the liquid outlet is provided in the valve seat, a valve core is clamped on the sealing plug, and a pressing part for lifting the valve core is provided on the valve core. A through opening is provided on the outer peripheral surface of the valve seat, and an end of the pressing part away from the valve core passes through the through opening. An upper cover is provided on the top of the valve seat, and a rotating ring is rotatably installed on the outer peripheral surface of the upper cover. A limiting part is fixed to the bottom surface of the rotating ring, and the bottom surface of the limiting part is in contact with the top surface of the pressing part.
[0004] With regard to the above-mentioned related technologies, when the user needs to open the wine valve and take out a large amount of wine, the staff rotates the rotating ring so that the rotating ring drives the limit part to move, so that the limit part moves to one side of the pressing part, and then the staff pulls up the pressing part, and the pressing part drives the valve core to move upward, and the valve core drives the sealing plug to move upward to open the wine valve. However, when taking out the wine, the user needs to pull the pull tab upward all the time, which causes the user's fingers to easily become sore when pulling the pull tab for a long time. Summary of the Invention
[0005] In order to improve the problem that the worker needs to keep pulling the pull tab during the process of liquid flowing out of the liquid outflow pipe, the present application provides a locking butterfly valve.
[0006] The locking butterfly valve provided in this application adopts the following technical solution: A locking butterfly valve comprises a valve seat, a liquid inlet pipe is provided on the side wall of the valve seat, the liquid inlet pipe is communicated with the valve seat, a liquid outlet is provided at the bottom end of the valve seat, a sealing plug is provided in the valve seat for sealing the liquid outlet, a valve core is clamped on the sealing plug, a lifting handle is provided on the outer peripheral surface of the valve core, a rotating ring is rotatably installed on the top end of the valve seat, a limiting portion is fixed to the bottom surface of the rotating ring, the bottom surface of the limiting portion abuts against the top surface of the lifting handle, and a fixing part for fixing the lifting handle is provided on the valve seat.
[0007] By adopting the above technical solution, when the butterfly valve needs to be opened, the rotating ring is rotated, and the rotating ring drives the limit part to move, so that the limit part is separated from the pulling handle, and the limit part moves to one side of the pulling handle. The user pulls the pulling handle upward, and the pulling handle drives the valve core to move upward, and the valve core drives the sealing plug to move upward, so that the liquid outlet is in an open state, allowing the red wine to flow out of the liquid outlet, and then the pulling handle is fixed by the fixing piece, thereby reducing the possibility of the user's fingers getting sore when the user lifts the lifting handle for a long time.
[0008] Preferably, a groove is formed on the outer peripheral surface of the protective ring, and the fixing member includes a spring sheet arranged in the groove, and the top end of the spring sheet can abut against the bottom surface of the pulling handle.
[0009] By adopting the above technical solution, when the lifting handle moves upward, the top end of the inner side surface of the lifting handle drives the spring piece to move toward the groove. When the spring piece detaches from the lifting handle, the spring piece moves out of the groove under the action of the elastic force, so that the top end of the spring piece abuts against the bottom surface of the lifting handle, so that the spring piece fixes the lifting handle when taking red wine.
[0010] Preferably, the side of the elastic piece away from the central axis of the valve seat is set as an inclined surface, and the distance between the top end of the inclined surface and the central axis of the valve seat is greater than the distance between the bottom end of the inclined surface and the central axis of the valve seat.
[0011] By adopting the above technical solution, when the lifting handle is lifted upward, the top end of the inner side surface of the lifting handle drives the inclined surface to move the inclined surface, thereby facilitating the movement of the elastic sheet into the groove.
[0012] Preferably, a movable groove is provided on the outer peripheral surface of the valve seat, and the fixing member includes a movable block slidably arranged in the movable groove. A push block is fixed on the side of the movable block away from the central axis of the valve seat, and the top surface of the push block can abut against the bottom surface of the pulling handle.
[0013] By adopting the above technical solution, when the lifting handle is lifted upward to open the butterfly valve, the push block is pushed toward the bottom of the lifting handle to move the push block to the bottom of the lifting handle. The top surface of the push block abuts against the bottom surface of the lifting handle, so that when the butterfly valve is in the open state, the push block limits the downward movement of the lifting handle.
[0014] Preferably, the inner top surface and the inner bottom surface of the movable groove are both provided with sliding grooves, and the top surface and the bottom surface of the movable block are both fixed with sliding blocks, and the sliding blocks are slidably arranged in the sliding grooves.
[0015] By adopting the above technical solution, when the push block moves, the push block drives the moving block to move, and the moving block drives the sliding block to move in the sliding groove, so that the push block moves more stably.
[0016] Preferably, both side surfaces of the push block are provided with arc surfaces.
[0017] By adopting the above technical solution, arc surfaces are provided on both sides of the push block, thereby increasing the contact area between the push block and the fingers of the staff, thereby facilitating the pushing of the push block.
[0018] Preferably, a plurality of tooth grooves are provided on the arc surface.
[0019] By adopting the above technical solution, a plurality of tooth grooves are provided on the arc surface, thereby increasing the friction between the arc surface and the fingers of the staff, making it easier to push the push block.
[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. When the butterfly valve needs to be opened, the rotating ring is rotated, which drives the limit part to move, so that the limit part is separated from the lifting handle and moves to one side of the lifting handle. The user pulls the lifting handle upward, which drives the valve core upward, and the valve core drives the sealing plug upward, so that the liquid outlet is in the open state, allowing the red wine to flow out of the liquid outlet. The lifting handle is then fixed with a fixing piece, thereby reducing the possibility of the user's finger pain when lifting the lifting handle for a long time. 2. When the handle moves upward, the top of the inner side of the handle drives the spring plate to move into the groove. When the spring plate is released from the handle, it moves out of the groove under the action of elastic force, so that the top of the spring plate abuts against the bottom of the handle, thereby securing the handle when taking red wine; 3. When the lifting handle is lifted upward to open the butterfly valve, push the push block toward the bottom of the lifting handle to move it below the lifting handle. The top surface of the push block abuts against the bottom surface of the lifting handle, so that when the butterfly valve is in the open state, the push block limits the downward movement of the lifting handle.

[0028] The following is combined with Figure 1-5 This application is described in further detail.
[0029] The embodiment of the present application discloses a locking butterfly valve.
[0030] Example 1 Reference Figure 1 and Figure 2 A locking butterfly valve includes a valve seat 1, and a liquid inlet pipe 11 is fixed to the outer peripheral surface of the valve seat 1, and the liquid inlet pipe 11 is connected to the valve seat 1. A liquid outlet 12 is provided at the bottom end of the valve seat 1, and a sealing plug 13 for sealing the liquid outlet 12 is provided at the inner bottom of the valve seat 1. The sealing plug 13 is made of rubber, and the outer peripheral surface of the sealing plug 13 fits the inner peripheral surface of the valve seat 1. A valve core 14 is clamped on the sealing plug 13, and two lifting handles 15 are integrally formed on the outer peripheral surface of the valve core 14. The two lifting handles 15 are symmetrically arranged along the central axis of the valve core 14. Two through openings 16 are provided on the outer peripheral surface of the valve seat 1, and the two through openings 16 correspond to the two lifting handles 15. The end of the lifting handle 15 away from the valve core 14 passes through the through opening 16.
[0031] Reference Figure 1 and Figure 2 A rotating ring 24 is rotatably mounted on the top of the valve seat 1. Two limiting portions 21 are fixed to the bottom of the rotating ring 24. The two limiting portions 21 are evenly spaced along the outer circumference of the rotating ring 24, and the bottom surfaces of the limiting portions 21 are aligned with the top surface of the lifting handle 15. Two mounting portions 2 are fixed to the top of the outer circumference of the valve seat 1. The two mounting portions 2 are spaced apart from the limiting portion 21 and are evenly spaced along the outer circumference of the valve seat 1. A positioning protrusion 22 is fixed to the side of the mounting portion 2 away from the valve seat 1. A receiving hole 23 is formed on the side of the limiting portion 21 near the positioning protrusion 22. The positioning protrusion 22 can be inserted into the receiving hole 23.
[0032] Reference Figure 1 and Figure 3The outer surface of the valve seat 1 is formed with two grooves 3, symmetrically arranged along the central axis of the valve seat 1, one on each side of the two openings 16. A spring 31 is mounted within each groove 3, the top of which can abut against the bottom of the handle 15. The side of the spring 31, away from the central axis of the valve seat 1, is formed with an inclined surface 32. The distance between the bottom of the inclined surface 32 and the central axis of the valve seat 1 is less than the distance between the top of the inclined surface 32 and the central axis of the valve seat 1.
[0033] The implementation principle of Example 1 is as follows: when the butterfly valve needs to be opened, the rotating ring 24 is rotated, and the rotating ring 24 drives the limit part 21 to move, so that the limit part 21 moves to the side of the lifting handle 15. The user lifts the lifting handle 15 upward, and the lifting handle 15 drives the valve core 14 to move upward. The valve core 14 drives the sealing plug 13 to move upward, so that the liquid outlet 12 is in an open state, and the red wine flows out from the liquid outlet 12. When the lifting handle 15 moves upward, the lifting handle 15 abuts against the inclined surface 32 on the elastic piece 31, and the lifting handle 15 pushes the elastic piece 31 to move toward the groove 3. When the lifting handle 15 is separated from the elastic piece 31, the elastic piece 31 moves out of the groove 3 under the action of the elastic force, so that the top surface of the elastic piece 31 abuts against the bottom surface of the lifting handle 15, so that the elastic piece 31 limits the lifting handle from moving downward, so that the user does not need to lift the lifting handle 15 for a long time when taking red wine, thereby reducing the possibility of soreness in the user's fingers.
[0034] When the butterfly valve needs to be closed, the spring piece 31 is moved toward the groove 3, so that the lifting handle 15 moves downward, and the lifting handle 15 drives the valve core 14 to move downward, and the valve core 14 drives the sealing plug 13 to move downward, so that the sealing plug 13 blocks the liquid outlet 12, and then the rotating ring 24 is rotated to make the rotating ring 24 drive the limiting part 21 to move above the lifting handle 15, so that the bottom surface of the limiting part 21 is in contact with the top surface of the lifting handle 15, thereby limiting the lifting handle 15 from moving upward, and then closing the butterfly valve.
[0035] Example 2 Reference Figure 4 、 Figure 5 and Figure 6The difference between this embodiment and embodiment 1 is that two movable grooves 4 are provided on the outer circumferential surface of the valve seat 1, and the two movable grooves 4 are respectively arranged on one side of the two openings 16. A movable block 41 is slidably provided in the movable groove 4, and the movable block 41 is slidably connected to the valve seat 1 along the circumference of the valve seat 1 through the movable groove 4. Sliding grooves 42 are provided on the inner top surface and the inner bottom surface of the movable groove 4, and sliding blocks 43 are fixed on the top surface and the bottom surface of the movable block 41, and the sliding block 43 is slidably provided in the sliding groove 42. A push block 44 is fixed to the end surface of the movable block 41 away from the central axis of the protective ring 23, and the top surface of the push block 44 can abut against the bottom surface of the lifting handle 15. Arc surfaces 45 are provided on both side surfaces of the push block 44, and a plurality of tooth grooves 46 are provided on the arc surface 45.
[0036] The implementation principle of Example 2 is: when the butterfly valve needs to be opened, the rotating ring 24 is rotated, and the rotating ring 24 drives the limit part 21 to move, so that the limit part 21 moves to the side of the lifting handle 15, and the user lifts the lifting handle 15 upward, and the lifting handle 15 drives the valve core 14 to move upward, and the valve core 14 drives the sealing plug 13 to move upward, so that the liquid outlet 12 is in an open state, and the red wine flows out from the liquid outlet 12, and then the push block 44 is pushed toward the bottom of the lifting handle 15, so that the push block 44 moves to the bottom of the lifting handle 15, and then the lifting handle 15 is opened, and the bottom surface of the lifting handle 15 abuts against the top surface of the push block 44, so that when the user takes the red wine, the push block 44 limits the lifting handle 15 from moving downward.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
